Ideally we should be seeing only diagonal elements with dark blocks.

Which models show most agreeability in predictions for all cells in our dataset?

What should we use?

Azimuth HLCA has 6 annotation-levels (Finest, L5, L4, L3, L2, L1)

CellTypist has 2 annotation-methods (individual Cell-Prediction, Majority-Voting among cell subclusters)

PopV has 8 individual predictions from heterogenous models and 1 ensemble prediction after majority-vote.
